Conducting a Hazard Assessment by Virginia Tech Environmental, Health and Safety Services Overview • What is a hazard assessment? • When is one required? • How do I conduct one? Definition • A hazard assessment is an evaluation of a work place, or work situation, as to the potential for hazards that an employee may encounter while performing the job. Requirements • Employers are required (by OSHA) to certify in writing that they have assessed the work place to determine if hazards that require personal protective equipment (PPE) are present or likely. Requirements • Employers are also required to: – Select and provide properly fitted protection from injury or impairment, and – Train employees in work area hazards and the proper use of PPE. PPE Coordinator • At VT, each department is required to appoint a coordinator to accomplish the task of performing a hazard assessment and overseeing that personal protective equipment is appropriate for the hazard and is being used accordingly. PPE Coordinator Responsibilities • • • • Perform the hazard assessment(s). Select appropriate PPE. Inform, fit, and train employees on PPE. Provide EHSS with required documentation. • Reassess the when new hazards are introduced. • Retrain employee if PPE is misused. Employee Responsibilities • Attend required PPE training sessions. • Wear PPE as required. • Clean, maintain, and properly care for PPE. • Inform PPE Coordinator if repair or replacement of equipment is needed. Where do you begin? • It is difficult to begin assessing every location, job title, or job task. The most logical place to begin is to review your accident and illness reports. – Is there a work area that seems to have more accidents and injuries than others? – Is there a type of injury that seems to occur more frequently than others? Where do you begin? • If injury and illness reports do not point you towards a place to begin, consider beginning with: – Close calls or near misses – New tasks or positions – Tasks that have changed – Non-routine jobs – Routine jobs Work Area Assessment • After you have chosen a place to start, perform a walk-through of the work area, looking for hazards as indicated in this training. Tip: Involve employees in this process to gain valuable input! Identify the Hazards • As you walk through the area and discuss work tasks with employees, look for the following hazards. – If you are unsure whether something should be included in your hazard assessment, contact EHSS for assistance or try using the reference material suggested on some of the slides. Falling Objects • Are there objects which may fall from above onto employees? – Employees working overhead? – Tools or materials handled above your head? Harmful Dusts/Mists/Fumes – Are employees exposed to chemicals or harmful dusts/mists/fumes? Examples: • • • • • Any chemical which poses a health hazard Asbestos Reference: Obtain a Material Welding fumes Safety Data Sheet on the Solder fumes product in question from the Silica supplier and review the information provided for health hazards and suggested controls. Energy Sources – Are there energy sources which could be harmful if accidental release or startup occurs? • • • • • • Electrical Pneumatic Hydraulic Thermal Mechanical Gravity Sharp Objects – Are there sharp objects which could cut or pierce the body? • • • • • • • Glass Knife blades Sheet metal Nail guns Needles Splinters (wood) Burrs (metal) Temperature Extremes – Are there hot or cold surfaces which could burn or freeze employees? • • • • • Welded parts Cryogenic materials Autoclaves Ovens/stoves Molten metals Light Radiation – Is there light radiation which could be harmful to the skin or eyes? • Welding and cutting • Lasers Flying Debris – Will employee be operating, or be exposed to, tools/equipment which may generate flying debris? • • • • • • Hammering Sawing Chipping Grinding Drilling Buffing Excessive Noise – Will employee be operating, or be exposed to, tools/equipment which may generate excessive noise? • • • • Jack-hammering Woodworking machinery Metalworking machinery Operating heavy equipment Workplace Layout – Does the layout of the workplace create a potential hazard? • Fall hazards exceeding 4 feet. • Low clearances • Confined spaces Fire/Explosion Hazards – Is there the potential for a fire or explosion? Step 2 • Once the hazard has been identified, you must implement an effective control to eliminate the hazard, reduce the hazard to an acceptable manner, or protect the employee. Step 3 • Evaluate the level of risk for each hazard to help determine what type of control should be implemented to reduce exposure. Step 4 • Select an appropriate solution to each hazard. – Always consider eliminating the hazard (if possible) first. – If elimination is not possible, consider reducing the hazard to an acceptable level. – If an acceptable level cannot be reached, select and provide appropriate personal protective equipment for the employee. Engineering Controls • Engineering controls eliminate exposure to the hazard. They are: – relatively permanent, – can be costly, and – can be time-consuming. Engineering controls are things that you do to fix the hazard. Isolation • Isolate the employee from the hazard. – Control rooms – Machine guarding – Protective barriers and shields – Guardrails – Clearance distances Design • Is there new (or existing) technology on the market for the product which, by it’s design, protects the person using it? Process Change • Can a non-hazardous process be substituted for a hazardous process? Spray Painting Dipping or Brushing Work Area Layout • Can a hazardous work area layout be improved? Hot Work Main Work Area Stacked Electrical Chemical Pipe Storage Storage Boxes Tool Room Work Area Layout • Chemical storage area was moved away from hot work and electrical hazards. Hot Work Stacked Electrical Boxes Pipe Chemical Storage Storage Main Work Area Tool Room Substitution • Can a non-hazardous product be substituted for a hazardous product? – Pesticides – Solder – Cleaning agents – Solvents Ventilation • Will ventilation improve the air quality to an acceptable (i.e. safe) level? Administrative Controls • Administrative controls reduce employee exposure to a hazard. – They do not eliminate the hazard, but they provide an acceptable way to work around the hazard. Reduction • Can you reduce the frequency of performing the hazardous task? Rotation • Can employees be rotated to reduce exposure time? Training • Can employees be trained to recognize hazards and employ safe work practices? Protect the Employee • If the hazard cannot be eliminated or reduced to an acceptable level, the employee must be protected from exposure. This protection requires that the employee wear and/or use appropriate personal protective equipment. Protect the Employee • • • • Hard hats Eye protection Face protection Respiratory protection • Hearing protection • • • • Body wear Sleeves Gloves Protective footwear Summary • Identify hazards in the workplace that could result in injury or illness. • Evaluate the level of risk to help determine what controls to implement. • Select an appropriate solution to control the hazard and/or protect the employee.
